Have you tried more than one Wii game?

If you have tried more than one Wii game and none will read,
This drive should fix any reading issues you are having with your games, or issues inserting your games or ejecting them (or lack thereof). This is the entire DVD drive assembly mechanism replacement for your Wii including a new laser. If your discs are not ejecting, or you cannot insert a disc -- or you can insert a disc but it will not load, this is what you need to get your Wii going again!

make sure that your wii is fully updated by connecting to the internet and doing a check for updates, some games need updates.

try removing all memory cards before starting a game, some games dont like the cards at first.

Your disc drive will need to be replaced, or you can mod your wii system at www.wiihdmods.com and get 100 wii games playable from a hard drive for 150.00

try the disk on a different wii and load the saved file on memory card and try it from there.if the game works fine with another account then the account that your trying to load is corrupted.if the game does read on a different system then it is your wii.(doubt it but is possible)if the game doesn't work with a new account then it is the cd.

Here is why Wii wants you to upgarde,

Wii wants you to upgarde since last ver. can not be hacked. So Wii makes people to upgarde by using the games, so that the more you upgarde the harder it is to hack the Wii. If Wii can be hacked, you can play copied games, you can go to blockbuter get a game, copy the game in computer and make copies at of it, so that you dont have to buy the game. And your wii is able to read the copied games

Now lets start with your problem,

Well now it will be even harder to downgrade the frimware of you Wii. (Wii doesnt want you to downgarde). Try to upragde it again if that doent work then upgarde it from the Wii's web page at Wii.com

There can be a problem in you Wii's upgardeded frimware.
